Overview

This document provides a comprehensive guide to the 78M6613 Evaluation Board, a platform designed for single-phase AC power and energy measurement. It utilizes the 78M6613 energy-meter controller to measure parameters including Watts, Volts, current, VAR, VA, phase angle, and power factor. The board features an isolated USB interface powered by an FTDI FT232R controller for PC connectivity via a serial UART interface. The manual includes installation instructions, safety guidelines regarding high-side reference topology, firmware details, electrical schematics, a full bill of materials, and PCB layouts.

Use Cases

  • Evaluation of the 78M6613 power measurement IC for accuracy and system integration.
  • Development of energy monitoring systems for single-phase AC loads.
  • Prototyping AC power measurement devices with isolated USB communication.
  • Reference for hardware design involving current shunts and voltage dividers in metering.
